unless the relevant statute provides such power to the authority. I notice that the decision of this Court in N.J Sebastian v. The District Collector, Kottayam District and others [2021 (5) KLT 745] specifically refers to the provisions of Section 13 of the Kerala Building Tax Act, 1975 and holds that the statute did not confer any power on the District Collector to entertain a revision petition which was not presented before the expiry of thirty days from the date on which the order of the assessing authority/appellate authority was communicated to him. It was therefore held relying on the binding judgments of this Apex Court that the District Collector cannot admit or entertain a revision petition presented beyond the said period, even if sufficient cause is shown for not presenting the same within the period.
